Different solutions are also presented in detail. Synchronous DRAM(SDRAM) is used as off-chip buffer to store-and-retransmission ethernet frames. A new and easy control design is introduced here. The buffer area size on chip is greatly reduced and the power dissipation is lowed at the same time.展开更多

The two-mode interference coupler and Mach-Zehnder interference are used to construct the filter chip. Simulation results of high isolation and low insertion loss are gotten for proposed design. Technique tolerance is improved for fabricating device.展开更多
